When does size-up begin?

• A. Upon arrival at the scene
• B. After initial risk assessment
• C. After securing the area
• D. When the company is dispatched

Answer: (D)

The main idea here is when you start assessing a scene to determine approach and safety: size-up is the ongoing evaluation of hazards, resources, and objectives that guides the plan. This starts the moment the unit is dispatched. From that moment, you begin gathering information from the dispatcher, any available call details, and pre-incident intel, and you start forming an initial plan. This early input lets you anticipate risks, estimate what resources you’ll need, and assign roles before you even arrive. You’ll keep refining this assessment as you respond, approach, and encounter new information on the scene. Arriving at the scene and securing the area are important steps too, but they’re part of continuing the size-up, not the starting point.
